Crest
Crest (krɛst)
Crest is a term used in various fields of medicine to denote a ridge or a raised surface on the anatomical structure of an organism. The term is derived from the Latin word "crista", which means "ridge".
Etymology
The term "crest" is derived from the Old French "creste", which is further derived from the Latin "crista", meaning "ridge" or "tuft". The term has been in use in the English language since the early 14th century.
In Anatomy
In anatomy, a crest refers to a ridge or a raised surface on the anatomical structure of an organism. For example, the iliac crest is the superior border of the wing of ilium, the largest of the three bones that merge to form the os coxa, or hip bone.
In Dentistry
In dentistry, the term crest is used to refer to the highest point of a curve. For example, the alveolar crest is the highest point of the alveolar ridge, which is the bony ridge in the upper or lower jaw that contains the sockets of the teeth.
In Pathology
In pathology, a crest can refer to a characteristic feature of a disease or condition. For example, in Crest syndrome, a rare autoimmune disease, the term CREST is an acronym for the five main features of the disease: Calcinosis, Raynaud's phenomenon, Esophageal dysmotility, Sclerodactyly, and Telangiectasia.
